The Best Way to Clean Windows (And Why Method Matters More Than You Think)

When people search for the best way to clean windows, they’re usually looking for one clear answer.

But in reality, it’s not just about how you clean—it’s about which method you choose. Different approaches can produce very different results, especially when it comes to streaks, durability, and long-term clarity.

Understanding the strengths and limitations of each method is what separates a short-term fix from a consistently clear finish.

Traditional Window Cleaning (By Hand)

Traditional window cleaning uses a cloth or applicator with a squeegee to remove water and solution from the glass.

This method is often considered the “classic” approach—and when done correctly, it can deliver excellent results.

Where it works best:

• Interior windows

• Ground-level glass

• Detailed or smaller panes

What to consider:

• The result depends heavily on technique

• Inconsistent pressure or poor blade control can leave streaks

• Edges and corners need to be finished manually

Traditional cleaning offers precision, but it requires a high level of consistency to achieve a flawless finish every time.

Purified Water Cleaning (Reach and Wash)

If you’re looking for the best way to clean exterior windows, especially at height, purified water cleaning is widely trusted by professional window cleaners for its consistency and safety.

This method uses a soft-bristled brush attached to a telescopic pole, allowing windows to be cleaned thoroughly from the ground. The water itself is purified to remove minerals and impurities, so it can dry naturally without leaving streaks or residue.

Where it works best:

• Exterior windows

• Upper floors and hard-to-reach areas

• Properties exposed to regular environmental build-up

Why it stands out:

• Eliminates mineral residue, reducing streaks

• Cleans both glass and frames in one process

• Delivers more consistent results over time

Which Should You Choose: Traditional vs Purified Water Cleaning

Rather than choosing one single technique, the best results often come from using the right method in the right situation.

For example:

• Interiors may benefit from traditional cleaning for a more detailed finish

• Exteriors often respond better to purified water systems

• Heavily soiled glass may require an initial deep clean before maintenance cleaning

This combined approach allows each method to do what it does best, rather than forcing one technique to cover everything.

The Role of Build-Up in Choosing the Right Method

Another key factor in determining the best way to clean windows is the level of build-up on the glass.

Light dust and everyday marks can usually be removed with standard cleaning methods. However, more stubborn issues such as mineral deposits, traffic film, or algae require a more targeted approach. 

If the method doesn’t match the type of dirt, the result is often compromised. You may find yourself moving residue around rather than removing it, leaving behind a cloudy finish, or needing to clean the windows again sooner than expected.

Choosing the right method from the start not only improves the immediate result but also helps maintain clarity for longer.
